Specification of Letters Patent.

Patented June 11, 1912.

Application filed October 28, 1908. Serial No. 459,923.

To all whom it may concern:

Be it known that I, ADoLPH FINOH, a citizen of the United States,residing at San Diego, in the county of San Diego and State ofCalifornia, have invented certain new and useful Propellers for Air orWater Craft; and I do hereby declare that the following is a full,clear, and exact description thereof, reference being had to theaccompanying drawings, which form a part of this specification.

My invention relates to mechanism for propelling aerial and waterlocomotives and for varying the direction of movement of aeriallocomotives laterally and upwardly and downwardly, and the objects of myinvention are to provide a propelling and raising and lowering mechanismwhich shall operate by resisting the atmosphere or water only during theeffective parts of its opera tive movements, but which shall offerlittle or no resistance to the atmosphere or water during the remainderor ineffective portion of its movement and further to provide amechanism that will cause the appliances when used for raising andlowering to stop in a longitudinal position thus providing a plane orfiat surface for sailing in the air. I attain these objects by themechanism illustrated in the accompanying drawings, in which Figure 1 isa plan view of the appliance as used for raising and lowering aeriallocomotives. Fig. 2 is a side elevation of the same. Fig. 3 is a planview of the appliance used as a longitudinal propeller for either aerialor water navigation; Fig. 1 is an end elevation thereof. Fig. 5 isadetailed longitudinal section of the spring roller. Fig. 6 is a detailelevational view of the wing regulating mechanism. 7 is a transverseelevational view thereof, and Fig. 8 is a perspective view of a portionthereof, drawn to a larger scale. 7

Similar characters of reference refer to similar parts throughout theseveral views.

The spring roller 1, the canvas 2 and the crank 3, constitute theprincipal parts of my invention and they involve in their com binedconstruction and operation the action of a wing which is adapted toresist the atmosphere or water during certain eifective portions of itsmovement and to operate without any appreciable resistance to atmosphereor water during the ineffective portion of its movement.

I have shown my appliance as it may be used in different ways. ,In Fig.1 I have shown it as applied on an airship for raising and lowering saidship and in Figs. 3 and 4: as longitudinal propellers for either air orwater navigation ships and used to propel the ship-forward or backwardas the case may be.

Numeral 1 represents a spring roller which is composed of a hollow tube1 which is attached at one end to a long torsional coil spring 1* whichin turn is attached at its other end to a central shaft 1 which extendscentrally through said spring and tube and acts as a bearing on whichthey revolve, To the outside of the hollow tube 1 and extending its fulllength is attached inthis case a canvas 2 of sufiicient length to reachfrom said spring roller 1 to and around crank 3 when the revolvingportion of said crank is farthest from said roller and which is looselyfastened around the crank 3. The crank 3 is a simple rod pivoted atpoints 3 and 3 and forming a U between said points. It can be seen thatwith this construction and the spring roller being wound and powercompelling the crank 3 to revolve outward and downward will cause thecanvas to be extended when out, the spring roller winding it up afterpassing the center downward. This will cause great resistance on theairor water on the extended and downward portion of its movement and littleor no resistance on theair'or water on the contracting and upwardportion of its move ment and by reversing its motion the effect would bethe opposite. I prefer to use these appliances in pairs in all cases byconnecting the crank by means of sprockets and chains 5 and Gas shown orany other convenient means and so connecting them that in one the canvaswill be extended and the spring wound and in the other the canvas willbe contracted and the spring unwound, the unwinding of one spring thusassisting in winding the other and vice versa.

i 'In Figs. 1 and 2, 8, 9 and 10 represent a convenient frame on which Iplace my .appliances for raising and lowering airships and of whichthere may be a plurality on each side of the center and all operated inunison by means of chain 11 from any driving mechanism over sprocket 12.I prefer to raise the rollers 1 upon braces 13 which will cause a moreinward thrust of the air upon the most eflicient portion of the stroketend ing to condense the air directly under the ship.

In Figs. 3 and 4 I show two sets set in position for either air or waterand placed on a frame composed of members 1 ll5 l6 and 17 andmanipulated in unison by means of sprockets and chains. I prefer toplace it on the front end of the ship propelled.

In Figs. ('3 and 7 I show a special sprocket 5 and lever attachments forthe manipulation of said sprockets. Said sprocket is made in two partsthe inner part 5 being keyed to the crank 3 and which is provided wit-han annular projection on its periphery adapted to fit loosely in arecess in the inner portion of the outer part 5 Upon the inner side ofsaid inner part 5 are double lugs 5 between which is pivoted a lever 5o-n pin 5*, said lever being provided with an outward extending lug 5adapted to fit into a recess 5 in a plate 5 which is fastened to outerpart 5 by means of screws, when said recess is in the right relativeposition, and saidlever 5 is provided with compression spring 5 adaptedto hold said lever crank in the position shown in Fig. 7. Upon theframepiece 9 I pivot a bellcrank 9 and connect to one member a wire 9for holding said bell crank out of contact with the path of lever 5 butI have provided a spring 9 to throw the bellcrank 9 in contact path oflever 5 upon the release of the wire 9 will be readily seen that withthis construction, the chain will keep the wing in motion at all timeswhile the wire 9' is taut, but when said wire is released, the spring 9will turn the bell-crank 9 so that the extended end of the other memberof said bell-crank projects beyond the edge of the frame support 9, sothat the port-ion including notch 9 will be in the path of the lever 5,which revolves with the inner part 5 of the sprocket. When the inner endof lever 5 in its revolution with part 5 engages with the angle surfaceof the extended end of the bell-crank, said inner end will be graduallydepressed thereby, causing the lug 5 on the outer end of said lever tobe thrown out of engagement with the recess in part 5* of said sprocket,and when said lever 5 reaches the notch 9 in said bell-crank member, itwill engage with said notch, and said lever having been released fromthe sprocket, will be held in said notch until released therefrom by thetightening of the cable 9 This will stop and hold the crank 3, (becauseof its rigid connection to the inner portion 5 of the sprocket), in theposition which will be the extended position of the wings, whichprovides for the simultaneous extension of all of the wings, therebyproviding a plane for sailing purposes, and by the tightening of thewire 9 the crank 3 will be caused to rotate when the outer part of thesprocket comes to a certain position, relatively to the inner portion.

Having thus described my invention, what I claim as new therein anddesire to secure by Letters Patent, is

1. A propelling appliance for aerial or Water locomotives, comprising, aframe, a torsional spring roller, a revoluble crank adj acent thereto, acanvas attached to said roller at one end and to said crank at its otherend, a sprocket on said crank and means in connect-ion with saidsprocket for facilitating the stopping of said crank in a certainposition in any revolution if so desired without stopping the motivepower, all substantially as set forth.
